An overdue routine communication from an archaeological team operating deep in the Ruber Desert requires investigation, and the Knights are given the task. What might have been a technical fault caused by recent solar storm activity turns out to be something far worse.

The archaeologists have made a discovery, perhaps the greatest discovery in human history. But what they found wasn't dead — it was only resting, waiting for the sign to reawaken.

Now, as a powerful storm sweeps over the archaeologists' base camp, the heroes are about to encounter something not seen in the universe for millions of years. There is no hope for rescue. There is only victory or death against a foe far more deadly than the Rephaim.

The Long Sleep is the first of a new series of Necropolis 2350 adventures from Triple Ace Games.
